. . , AUTOMATED COMMUNICATION LINE SWITCHING FOR VOICEMAIL ACCESS
[0001] The present invention relates generally to telephone station apparatus
adapted to use more than one telephone communication line and, more
specifically,
to the selection of a communication line to use to check voicemail messages.
[0002] To satisfy mobile telephony device users that wish to use the same
mobile telephony device for two purposes, a feature has been developed for the
Global System for Mobile Communications (GSM) standard called "Alternate Line
Service" or "ALS". ALS allows a single mobile telephony device to support two
different destination numbers. More particularly, since all GSM mobile
telephony
devices operate in conjunction with a Subscriber Identity Module (SIM),
commonly
known as a SIM card, ALS allows a single SIM card to support two different
destination numbers. Separation of work-related and personal telephone calls
is a
primary application for ALS.
[0003] Another telephony standard, called Code Division Multiple Access, or
"CDMA", also allows a single mobile telephony device to support two different
destination numbers. CDMA telephony devices may have a dual-NAM feature or a
multi-NAM feature offering users the option of registering the telephony
device with a
local number in more than one market. A NAM is a Number Assignment Module, the
electronic memory in the cellular phone that stores the destination number and
an
electronic serial number.
[0004] A mobile telephony device that supports two, or more, different
destination numbers, and, accordingly, is associated with two, or more,
communication lines, can only have a single communication line active at one
time.
Typically, a series of key presses is all that is necessary to switch the
active
communication line from one communication line to the other.
[0005] For most mobile telephony systems, voicemail messages are stored by a
central voicemail server. Often a caller is connected to the voicemail server
CA 02627797 2008-03-31
-2-
responsive to a failure to complete a connection to a mobile telephony device,
where
the user of the mobile telephony device subscribes to a voicemail messaging
service. Under typical (single communication line) circumstances, once a
voicemail
message has been stored at the voicemail server, the voicemail server sends an
indication of the waiting voicemail message to the mobile telephony device.
The
mobile telephony device may, responsive to receiving. such an indication,
signal to
the user that the voicemail server has at least one voicemail message waiting.
For
instance, the signal may be a persistent icon on a part of a display screen of
the
mobile telephony device. The user may then use the mobile telephony device to
place a call to the voicemail server and review the waiting voicemail message.
The
voicemail server uses Calling Line Identification (CLID) to associate an
incoming call
with a voicemail box and, once the user is authenticated, presents the waiting
voicemail message to the user.
[0006] Under circumstance related to having a voicemail message to retrieve
from a telephony device configured to have two, or more, communication lines,
the
user will first have to determine with which of the communication lines the
voicemail
message is associated. If the user determines that the voicemail message is
associated with the active communication line, the user may simply perform
standard
actions necessary to contact the voicemail server and review the waiting
voicemail
message. However, if the user determines that the voicemail message is
associated
with a communication line that is not active, the user must take the steps to
make the
communication line active before performing standard actions necessary to
contact
the voicemail server and review the waiting voicemail message. Upon completion
of
the call to the voicemail server, the user is required to take the manual
steps
necessary to switch back the originally active communication line, assuming
that the
originally active communication line is the preferred line at the time.
[0007] It appears that the act of accessing voicemail on a telephony device
that
is configured to have two, or more, communication lines may be considered
somewhat onerous.
CA 02627797 2008-03-31

GENERAL
[0008] A telephony device that is configured to have two, or more,
communication lines may receive an indication that a voicemail message is
waiting
at a voicemail server and with which of the communication lines the message is
associated. Where the communication line with which the message is associated
is
not the active communication line, and responsive to receiving an instruction
to
access the voicemail server, the telephony device automatically switches from
the
active communication line to the communication line with which the message is
associated and initiates a call to the voicemail server.
[0009] Advantageously, the user need not manually switch the active
communication line to access the voicemail server. Further advantageously, the
user
need not know which communication line to use to access the voicemail server.
[0010] According to one aspect, there is provided a method of providing a user
interface on a telephone station apparatus, the user interface facilitating
selection, by
a user, of an active communication line for calling a voicemail server, the
telephone
station apparatus providing access to a first communication line and a second
communication line having voicemail message storage associated therewith at
the
voicemail server. The method includes receiving an input from the user, the
input
including an instruction to access the voicemail server, determining that the
first
communication line is the active communication line, switching, responsive to
the
determining, from the first communication line to the second communication
line, and
initiating a call, on the second communication line, to the voicemail server.
Additionally, a telephone station apparatus is provided for carrying out this
method
and a computer readable medium is provided for containing instructions to
allow a
processor to carry out this method.
[0011] Other aspects and features will become apparent to those of ordinary
skill
in the art upon review of the following description of examplary embodiments
in
conjunction with the accompanying figures.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0020] As used herein, the term "examplary embodiment" is used merely to
indicate that an embodiment serves as an example and it should not be
considered
that the example is, in any way, a preferred embodiment.
CA 02627797 2008-03-31
-5-
[0021] Reference is now made to FIG. 1, which illustrates elements of an
examplary network environment 100 for the operation of a mobile telephone
station
apparatus 101. The elements of the examplary network environment 100 include a
wireless carrier network 116 and a telephony and data communication network
108.
[0022] The telephony and data communication network 108 may be considered
to represent at least one wide area network, such as the present day Internet
and
successor networks, as well as, potentially, multiple local area networks and
a public
switched telephone network (PSTN).
[0023] The wireless carrier network 116 includes a base station subsystem 104
and a wireless network subsystem 106. A base station antenna 102, with which
the
mobile telephone station apparatus 101 may communicate wirelessly, is provided
as
part of the base station subsystem 104. The base station subsystem 104
connects to
a wireless network subsystem 106. The wireless network subsystem 106, which
may
include, in part, a Mobile-services Switching Center (MSC), is connected to
the
telephony and data communication network 108.
[0024] Also connected to the telephony and data communication network 108 is
a voicemail server 110 for performing voicemail services, such as receiving,
storing,
and providing voicemail messages.
[0025] A central office 112 allows a traditional land-line telephone station
apparatus 114 to connect to and utilize the telephony and data communication
network 108. Additionally, the land-line telephone station apparatus 114 can
connect
to the voicemail server 110. The land-line telephone station apparatus 114 can
access the data communication network 108 or voicemail server 110 by an input
device such as a keypad (not shown).
[0026] FIG. 2 illustrates the mobile telephone station apparatus 101 including
a
housing, an input device (such as a keyboard 224 or a navigation tool (not
shown)),
and an output device (a display 226), which is preferably a full graphic or
full color
CA 02627797 2008-03-31
-6-
Liquid Crystal Display (LCD). Other types of output devices may alternatively
be
utilized. A processing device (a microprocessor 228) is shown schematically in
FIG.
2 as coupied between the keyboard 224 and the dispiay 226. The microprocessor
228 controls the operation of the display 226, as well as the overall
operation of the
mobile telephone station apparatus 101, in response to actuation of keys on
the
keyboard 224 by a user.
[0027] The housing may be elongated vertically, or may take on other sizes and
shapes (including clamshell housing structures). The keyboard may include a
mode
selection key, or other hardware or software, for switching between text entry
and
telephony entry.
[0028] In addition to the microprocessor 228, other parts of the mobile
telephone
station apparatus 101 are shown schematically in FIG. 2. These include: a
communication subsystem 202; a short-range communication subsystem 204; the
keyboard 224 and the display 226, along with other input/output devices
including a
set of auxiliary input/output devices 206, a serial port 208, a speaker 211
and a
microphone 212; as well as memory devices including a flash memory 216 and a
Random Access Memory (RAM) 218; and various other device subsystems 220. The
mobile telephone station apparatus 101 may have a battery 222 to power the
active
elements of the mobile telephone station apparatus 101. The mobile telephone
station apparatus 101 is preferably a two-way radio frequency (RF)
communication
device having voice and data communication capabilities. In addition, the
mobile
telephone station apparatus 101 preferably has the capability to communicate
with
other computer systems via the Internet.
[0029] Operating system software executed by the microprocessor 228 is
preferably stored in a computer readable medium, such as the flash memory 216,
but may be stored in other types of memory devices, such as a read only memory
(ROM) or similar storage element. In addition, system software, specific
device
appiications, or parts thereof, may be temporarily loaded into a volatile
store, such as
CA 02627797 2008-03-31
-7-
the RAM 218. Communication signals received by the mobile device may also be
stored to the RAM 218.
[0030] The microprocessor 228, in addition to its operating system functions,
enables execution of software applications on the mobile telephone station
apparatus 101. A predetermined set of software applications that control basic
device operations, such as a voice communications module 230A and a data
communications module 230B, may be installed on the mobile telephone station
apparatus 101 during manufacture. A line switching module 230C may also be
installed on the mobile telephone station apparatus 101 during manufacture, to
implement aspects of the invention. As well, additional software modules,
illustrated
in FIG. 2 as other software module 230N, which may be, for instance, a
personal
information manager (PIM) application, may be installed during manufacture.
The
PIM application is preferably capable of organizing and managing data items,
such
as e-mail messages, calendar events, voice mail messages, appointments, and
task
items. The PIM application is also preferably capable of sending and receiving
data
items via the wireless carrier network 116. Preferably, the data items managed
by
the PIM application are seamiessly integrated, synchronized and updated via
the
wireless carrier network 116 with the device user's corresponding data items
stored
or associated with a host computer system.
[0031] Communication functions, including data and voice communications, may
be performed through the communication subsystem 202 and, possibly, through
the
short-range communication subsystem 204. The communication subsystem 202
includes a receiver 250, a transmitter 252 and one or more antennas,
illustrated in
FIG. 2 as a receive antenna 254 and a transmit antenna 256. In addition, the
communication subsystem 202 also includes a processing module, such as a
digital
signal processor (DSP) 258, and local oscillators (LOs) 260. The specific
design and
implementation of the communication subsystem 202 is dependent upon the
communication network in which the mobile telephone station apparatus 101 is
intended to operate. For example, the communication subsystem 202 of the
mobile
CA 02627797 2008-03-31
-8-
telephone station apparatus 101 may be designed to operate with the MobitexT""
DataTACTM or General Packet Radio Service (GPRS) mobile data communication
networks and may also be designed to operate with any of a variety of voice
communication networks, such as Advanced Mobile Phone Service (AMPS), Time
Division Multiple Access (TDMA), CDMA, Personal Communications Service (PCS),
GSM, etc. Other types of data and voice networks, both separate and
integrated;
may also be utilized with the mobile telephone station apparatus 101.
[0032] When required network registration or activation procedures have been
completed, the mobile telephone station apparatus 101 may send and receive
communication signals over the wireless carrier network 116. Signals received
from
the base station antenna 102 by the receive antenna 254 are routed to the
receiver
250, which provides for signal amplification, frequency down conversion,
filtering,
channel selection, etc., and may also provide analog to digital conversion.
Analog-to-
digital conversion of the received signal allows the DSP 258 to perform more
complex communication functions, such as demodulation and decoding. In a
similar
manner, signals to be transmitted to the base station antenna 102 are
processed
(e.g., modulated and encoded) by the DSP 258 and are then provided to the
transmitter 252 for digital to analog conversion, frequency up conversion,
filtering,
amplification and transmission to the base station antenna 102 via the
transmit
antenna 256.
[0033] In addition to processing communication signals, the DSP 258 provides
for control of the receiver 250 and the transmitter 252. For example, gains
applied to
communication signals in the receiver 250 and the transmitter 252 may be
adaptively
controlled through automatic gain control algorithms implemented in the DSP
258.
[0034] In a data communication mode, a received signal, such as an SMS
message or web page download, is processed by the communication subsystem 202
and is input to the microprocessor 228. The received signal is then further
processed
by the microprocessor 228 in preparation for output to the display 226, or
CA 02627797 2008-03-31
-9-
alternatively to some other auxiliary I/O devices 206. A device user may also
compose data items, such as e-mail messages or SMS messages, using the
keyboard 224 and/or some other auxiliary I/O device 206, such as a touchpad, a
rocker switch, a thumb-wheel, or some other type of input device. The composed
data items may then be transmitted to the base station antenna 102 via the
communication subsystem 202.
[0035] In a voice communication mode, overall operation of the device is
substantially similar to the data communication mode, except that received
signals
may be output to the speaker 211, and signals for transmission may be
generated by
the microphone 212. Alternative voice or audio I/O subsystems, such as a voice
message recording subsystem, may also be implemented on the mobile telephone
station apparatus 101. In addition, the display 226 may also be utilized in
voice
communication mode, for example, to display the identity of a calling party,
the
duration of a voice call, or other voice call related information.
[0036] The short-range communication subsystem 204 enables communication
between the mobile telephone station apparatus 101 and other proximate systems
or
devices, which need not necessarily be similar devices. For example, the short-
range communication subsystem 204 may include an infrared device and
associated
circuits and components, or a BluetoothT " communication module, to provide
for
communication with similarly-enabled systems and devices.
[0037] The conditions for receiving a voicemail message are generally well
known. In the case of the land-line telephone station apparatus 114 (shown in
FIG.
1), an incoming call to a called communication line may be redirected, by the
central
office 112, to the voicemail server 110 when the called communication line is
engaged in another call (i.e., the communication line is busy) or when the
called
communication line is not answered after a predetermined number of rings.
These
two conditions also apply for the mobile telephone station apparatus 101.
Additionally, an incoming call may be redirected to the voicemail server 110
when
CA 02627797 2008-03-31
-10-
the mobile telephone station apparatus 101 to which the incoming call is
destined is
"out of service". When out of service, the mobile telephone station apparatus
101
may be turned off or may be in a place that limits the ability for the mobile
telephone
station apparatus 101 to communicate wirelessly with the base station antenna
102.
In both fixed and wireless cases, a voicemail message may be generated within
the
voicemail server 110 by another user of the voicemail server and then stored
in a
destination voicemail box on the voicemail server 110.
[0038] When a voicemail message is in a voicemail box and has yet to be
reviewed, the voicemail server 110 will typically indicate a "voicemail
message
waiting" condition to the telephone station apparatus 101 or 114 associated
with the
voicemail box. In the case of the land-line telephone station apparatus 114,
often the
dial tone on th'e communication line is made to stutter. Upon recognition of
the
stuttered dial tone by a telephone station apparatus 114 connected to the
communication line, the telephone station apparatus 114 generates an external
indication of a voicemail message awaiting consideration by the user. Often,
the
external indication is a flashing light. In the case of the mobile telephone
station
apparatus 101, it is typical that only one mobile telephone station apparatus
101 is
associated with a telephone communication line. Accordingly, indicating on the
communication line means indicating to the mobile telephone station apparatus
101.
In the GSM, such indicating is typically performed using the Short Messaging
Service (SMS). That is, the voicemail server 110 sends an SMS message to the
mobile telephone station apparatus 101 indicating that a new voicemail message
is
available for review. The mobile telephone station apparatus 101, responsive
to
receiving such a message, can indicate, for example, by way of presenting a
voicemail waiting sign on the display 226, that a new voicemail message is
waiting.
In some instances, the voicemail waiting sign can be specific to the
communication
line for which the voicemail message has been received.
[0039] In the ALS (GSM) case, a voicemail server 110 can indicate to a mobile
telephone station apparatus 101 that a new voicemail message is waiting for
the
CA 02627797 2008-03-31
-11-
non-active communication line. Conversely, in the dual-NAM (CDMA) case, the
non-
active communication line is invisible to the base stations and, accordingly,
a mobile
telephone station apparatus 101 with communication line 1 active will not
receive
notification of a new voicemail message on communication line 2.
[0040] When a mobile telephone station apparatus 101 receives an indication of
a new voicemail message, the mobile telephone station apparatus 101 generally
presents an indication to the user that a new voicemail message is waiting. It
is
typical that the indication to the user, say, through the use of an icon on a
display,
specifies which of the multiple communication lines with which the voicemail
message notification is associated.
[0041] The steps necessary to contact the voicemail server 110 from a
telephone
station apparatus 101 or 114 are known to be many and varied. For instance, a
mobile telephone station apparatus 101 may be arranged to initiate a call to
the
voicemail sever 110 responsive to an extended press on the "1" button. In
another
case, a user of a mobile telephone station apparatus 101 may configure a
"speed
dial" number or a "voice dial" command to quickly initiate a call to the
voicemail
server 110. In a further case, a user of a mobile telephone station apparatus
101
may actuate an input device such as a keyboard 224 (shown in FIG. 2), thereby
causing a menu to appear as part of a user interface presented on a display
226
(shown in FIG. 2) of the mobile telephone station apparatus 101. One of the
menu
items on the menu may be "Call Voicemail". In the case of a land-line
telephone
station apparatus 114, a call to the voicemail server 110 can be initiated by
dialing
the sequence ' 9 8" on a keypad of the land-line telephone station apparatus
114.
[0042] In the case wherein the telephone station apparatus 101 or 114 is
configured to have two, or more, communication lines, whichever communication
line
is active at the time at which the user instructs the telephone station
apparatus 101
or 114 to access the voicemail server 110 will be the communication line that
is used
to place a call to the voicemail server 110 associate with the communication
line.
CA 02627797 2008-03-31
-12-
The CLID of the incoming call to the voicemail server 110 is used by the
voicemail
server 110 to select a voicemail box the contents of which may be reviewed by
the
caller.
[0043] However, when the new voicemail message for which an indication has
been displayed is associated with a non-active communication line, a call to
the
voicemail server 110 will allow the user to review messages in the voicemail
box
associated with the active communication line. Consequently, the voicemail
server
will 110 not allow the user to review the new voicemail message associated
with the
non-active communication line.
[0044] Upon determining that a new voicemail message is waiting for user
consideration and is associated with the communication line that is not
active, the
user typically takes the steps necessary to make the other communication line
active
before performing actions necessary to contact the voicemail server 110 and
review
the waiting voicemail message. Upon completion of the call to the voicemail
server
110, the user is required to take the steps necessary to switch back the
originally
active communication line, assuming that the originally active communication
line is
the preferred communication line at the time.
[0045] In overview, a user may receive, at a telephone station apparatus 101
or
114, an indication that a new voicemail message is waiting at the voicemail
server
110 for review by the user. Where the communication line with which a waiting
voicemail message is associated is not the active communication line and
responsive to receiving an instruction to access the voicemail server 110, the
telephone station apparatus 101 or 114 automatically switches from the active
communication line to the communication line with which the message is
associated
and initiates a call to the voicemail server 110.
[0046] In one examplary embodiment, selection of the "Call Voicemail" menu
item invokes presentation of a pop-up dialog box showing a graphic button
associated with each of the communication lines associated with the telephone
CA 02627797 2008-03-31
-13-
station apparatus 101 or 114. The user may then employ an input device (such
as a
keyboard 224, a navigation tool or a keypad) to select one of the graphic
buttons,
thereby instructing the telephone station apparatus 101 or 114 which
communication
line to use to access the voicemail server 110. Responsively, the telephone
station
apparatus 101 or 114 switches, if necessary, to the selected communication
line and
initiates a call to the voicemail server 110. Furthermore, to give the user
additional
information, each communication line-associated graphic button in the dialog
box
may include an additional sign, where the sign signifies that a voicemail
message
waiting indication has been received from the voicemail server 110, which
indication
is associated with the communication line associated with the graphic button
having
the additional sign.
[0047] If the active communication line does not have a voicemail on it and
the
non-active communication line does, the user can simply press the voicemail
speed-
dial button and the telephone station apparatus 101 or 114 will change the
communication line automatically for the user and dial the number (with any
additional tones). After the call has been completed, the telephone station
apparatus
101 or 114 can optionally switch back to the original active communication
line.
[0048] Reference is now made to FIG. 3, which illustrates examplary steps in a
method of placing a call, on a communication line associated with a voicemail
message, to the voicemail server 110 (shown in FIG. 1). The telephone station
apparatus 101 or 114 (shown in FIG. 1) that is to perform the examplary steps
of
FIG. 3 is associated with two examplary communication lines: a Business line;
and a
Personal line. In the presently described examplary embodiment, the telephone
station apparatus 101 or 114 has been configured so that the Personal line is
active
and the telephone station apparatus 101 or 114 has received at least one
indication
from the voicemail server 110 that a voicemail message is awaiting
consideration by
user. However, it can be appreciated that the method can be implemented on a
telephone station apparatus 101 or 114 having multiple communication lines,
with
CA 02627797 2008-03-31
-14-
one or more communication lines having voicemail message services associated
therewith.
[0049] While the examples presented hereinafter. focus on the mobile telephone
station apparatus 101, it should be clear to a person of ordinary skill in the
art that
the discussion applies equally to the land-line telephone station apparatus
114.
Further, while components of the mobile telephone station apparatus 101 have
been
discussed and presented in FIG. 2, it should be clear that many of the same
components (e.g., the display 226, the microprocessor 228, the auxiliary I/O
devices
206) may be found in the land-line telephone station apparatus 114.
[0050] In operation, a user of the telephone station apparatus 101 or 114 may
be
prompted to call the voicemail server 110. The prompting may take the form of
the
previously discussed stuttering dial tone or an icon presented on the display
226.
Responsive to the prompting, a user of the telephone station apparatus 101 or
114
manipulates a telephone station apparatus input device (such as the keyboard
224 in
FIG. 2 or a keypad) to give an instruction to the telephone station apparatus
101 or
114 to place a call to the voicemail server 110. As discussed hereinbefore,
the user
may, for instance, manipuiate the input device to cause a menu to appear on
the
user interface on the display 226. Subsequently, the user may, through further
input
device manipulation, select a menu item "Call Voicemail". The telephone
station
apparatus, or, more precisely, the microprocessor 228 of the mobile telephone
station apparatus 101, receives the instruction (step 302) and, responsive to
receiving the instruction, determines (steps 304, 308) which communication
line (or
communication lines) is associated with the waiting voicemail message.
[0051] In the case wherein the waiting voicemail message is only associated
with
one communication line, as determined in step 304, the microprocessor 228
determines (step 308) whether the waiting voicemail message is associated with
the
active communication line.
CA 02627797 2008-03-31
-15-
[0052] In the case wherein the waiting voicemail message is associated with
the
communication line that is not active, the microprocessor 228 arranges (step
320)
the presentation of a dialog, on the display 226, that gives the user an
opportunity to
select which of the two communication lines to employ to access the voicemail
server 110. A first examplary dialog 400 is illustrated in FIG. 4. As
illustrated in FIG.
4, a default selection 402 is provided as the communication line that is
associated
with the waiting voicemail message. For this example, the waiting voicemail
message is associated with the Personal line, as indicated by a voicemail
waiting
sign 404 associated with the graphic button 402 that represents the Personal
line.
Accordingly, the graphic button 402 that represents the Personal line is the
default
selection in the first examplary dialog 400. Note that the first examplary
dialog 400,
illustrated in FIG. 4, includes an active communication line indicator 406 to
remind
the user which of the available communication lines is active.
[0053] Upon receiving (step 312) a selection from user of a communication line
15, (in the presently described examplary embodiment the Personal line) to
employ to
access the voicemail server 110, the microprocessor 228 determines (step 314)
whether the selected communication line is the active communication line.
[0054] In the case wherein the microprocessor 228 determines (step 314) that
the selected communication line is the not the active communication line, the
microprocessor 228 switches communication lines (step 318) such that the
selected
communication line becomes the active communication line. That is, the
microprocessor 228 makes the selected communication line active. The
microprocessor 228 then initiates (step 316) a call to the voicemail server
110.
[0055] At the voicemail server 110, the incoming call is received and
answered.
According to the CLID information associated with the incoming call, the
voicemail
server 110 presents the incoming call with access to the voicemail box
associated
with the Personal line. As is customary, the user is likely to be required to
CA 02627797 2008-03-31
-16-
successfully complete an authentication procedure before being allowed to
review
the waiting voicemail message.
[0056] After determining, in step 304, that the waiting voicemail message is
only
associated with one communication line, the microprocessor 228 may determine
(step 308) that the waiting voicemail message is associated with the active
communication line.
[0057] In the case wherein the waiting voicemail message is associated with
the
active communication line, the microprocessor 228 arranges (step 310) the
presentation of a dialog that gives the user an opportunity to select which of
the two
communication lines to employ to access the voicemail server 110. A second
examplary dialog 500 is illustrated in FIG. 5. As illustrated in FIG. 5, a
default
selection 502 is provided as the communication line that is associated with
the
waiting voicemail message. For this example, the waiting voicemail message is
associated with the Personal line. Accordingly, the graphic button 502 that
represents the Personal line is the default selection in the second examplary
dialog
500.
[0058] Upon receiving (step 312) a selection of a communication line (in the
presently described examplary embodiment, the selected communication line is
the
Personal line) to employ to access the voicemail server 110, the
microprocessor 228
determines (step 314) whether the selected communication line is the active
communication line.
[0059] In the case wherein the microprocessor 228 determines (step 314) that
the selected communication line is the active communication line, the
microprocessor 228 need not switch to the selected communication line. That
is, the
microprocessor proceeds with the selected communication line active. The
microprocessor then initiates (step 316) a call to the voicemail server 110.
CA 02627797 2008-03-31

[0060] At the voicemail server 110, the incoming call is received
and.answered.
According to the CLID information associated with the incoming call, the
voicemail
server 110 presents the incoming call with access to the voicemail box
associated
with the Personal line. As is customary, the user is likely to be required to
successfully complete an authentication procedure before being allowed to
review
the waiting voicemail message.
[0061] In the case wherein waiting voicemail messages are associated with both
communication lines, as determined in step 304, the microprocessor 228 need
not
determine which communication line to associate with the waiting voicemail
message. Rather, the microprocessor 228 arranges (step 306) the presentation
of a
dialog that gives the user an opportunity to select which of the two
communication
lines to employ to access the voicemail server 110. A third examplary dialog
600 is
illustrated in FIG. 6. As illustrated in FIG. 6, a default selection 602 is
the active
communication line. For this example, the waiting voicemail message is
associated
with the both communication lines and the Personal line is active.
Accordingly, the
graphic button 602 that represents the Personal line is the default selection
in the
second examplary dialog 600.
[0062] Upon receiving (step 312) a selection of a communication line (in the
presently described examplary embodiment, the selected communication line is
the
Personal line) to employ to access the voicemail server 110, the
microprocessor 228
determines (step 314) whether the selected communication line is the active
communication line.
[0063] In the case wherein the microprocessor 228 determines (step 314) that
the selected communication line is the active communication line, the
microprocessor 228 initiates (step 316) a call to the voicemail server 110.
[0064] At the voicemail server 110, the incoming call is received and
answered.
According to the CLID information associated with the incoming call, the
voicemail
server 110 presents the incoming call with access to the voicemail box
associated
CA 02627797 2008-03-31
-18-
with the Personal line. As is customary, the user is likely to be required to
successfully complete an authentication procedure before being allowed to
review
the waiting voicemail message.
[0065] Steps in an examplary method of handling the end of a call to the
voicemail server 110 are illustrated in FIG. 7.
[0066] Referring to FIG. 7, in one examplary embodiment, while the call to the
voicemail server 110 is ongoing, the microprocessor 228 monitors the call to
determine (step 702) whether the call is complete. If it is determined that
the call
continues, the monitoring (step 702) also continues. If it is determined that
the call is
complete, the microprocessor 228 then determines (step 704) whether a switch
to
another c.~ommunication line has occurred before the call to the voicemail
server 110.
[0067] To prepare for the determination that may be made in step 704, the
microprocessor 228 may, as part of step 318 wherein the microprocessor 228
performs a switch such that a selected communication line becomes the active
communication line, record at least two items of information. In particular,
the
microprocessor 228 may record: (1) that a switch has been performed; and (2)
an
identity of the formerly active communication line.
[0068] If the microprocessor 228 determines (step 704) that a switch to
another
communication line did not occur before the call to the voicemail server 110
(i.e., the
call to the voicemail server 110 was made on the already active communication
line),
no switch back to a formerly active communication line is necessary. However,
if the
microprocessor 228 determines (step 704) that a switch to another
communication
line has occurred before the call to the voicemail server 110, the
microprocessor 228
can use the recorded identity of the formerly active communication line and
perform
a switch (step 706) back to the identified communication line.
[0069] As illustrated in each of FIGS. 4, 5 and 6, when a dialog is presented
to
provide a choice of communication lines to be used to access the voicemail
server
CA 02627797 2008-03-31
-19-
110, one of the communication lines is pre-selected as a default communication
line.
Where only one communication line has one or more voicemail messages waiting,
that communication line is pre-selected as the default communication line.
Where
more than one communication line has one or more voicemail messages waiting
and
the active communication line has one or more voicemail messages waiting, the
microprocessor 228 may pre-select the active communication line as the default
communication line. In alternative embodiments, where more than one
communication line has one or more voicemail messages waiting, the
microprocessor 228 may pre-select the communication line having more voicemail
messages waiting than other available communication lines as the default
communication line. Further alternatively, where more than one communication
line
has one or more voicemail messages waiting, the microprocessor 228 may pre-
select the communication line having more recent voicemail messages waiting
than
other available communication lines as the default communication line.
[0070] As is known, while employing ALS, the mobile telephone station
apparatus 101 with the Business line set to be the active communication line,
as
illustrated by active communication line indicator 406 in the examplary
embodiment
of FIG. 4, may receive a notification that a voicemail message is waiting at
the
voicemail sever 110. The notification may indicate that the voicemail message
is
associated with either the Business line or the Personal line.
[0071] In contrast, while employing dual-NAM, the mobile telephone station
apparatus 101 with the Business line set to be the active communication line
may
only receive notifications that a voicemail message is waiting at the
voicemail sever
110 for the Business line. Any notifications generated at the voicemail sever
110 for
the Personal line will not reach the dual-NAM mobile telephone station
apparatus
101 until the dual-NAM mobile telephone station apparatus 101 is switched to
the
Personal line.
